A positive charge q is fixed at the pointx=0,y=0 and a negative charge -2q isfixed at the point x=a,y=0.
Part A:
Derive an expression for the potential V at points onthe y-axis as a function of the coordinate y.Take V to be zero at an infinite distance from thecharges.
Part B:
At which positions on the y-axis is V = 0?
Part C:
What does the answer to part A become wheny>>a?
